A former aide of Congressman Tom Delay is expected to plead guilty today to conspiring with Republican lobbyist Jack Abramoff to bribe government officials, including a congressman, and bilk millions of dollars from Native American tribes. The official, Michael Scanlon, worked as a press aide to Delay and later became a prominent public relations executive. He has reportedly agreed to work with federal prosecutors investigating Abramoff. Scalon is accused of working with Abramoff in a scheme in which the lobbyist would direct tribes to hire Scanlon’s public relations firm without telling them Scanlon had agreed to kick back half of the profits to Abramoff. The pair received $82 million in lobbying and public relations fees from half a dozen tribes. Prosecutors charge that Scanlon and Abramoff conspired to bribe Republican Congressman Robert Ney of Ohio who is referred to in the charging document as “Representative #1.” Thomas Mann, a Congressional specialist at the Brookings Institution said “I think this has the potential to be the biggest scandal in Congress in over a century. Meanwhile newly disclosed documents show that Abramoff asked the president of the West African nation of Gabon for $9 million in order to set up a White House meeting with President Bush.
